SEO – generally means “search engine optimization” or “search engine optimizer.”
Rank – a website page’s position in the free search engine results for a particular search term. The search term is the fundamental point here since the concept of rank is relative to a search term and is pretty meaningless in this context otherwise ie. a page that ranks #1 in Google may only rank #1 for one specific search term (keyword)
NOTE: remember that Google ranks pages not sites
SERP – search engine result page
PageRank – not to be confused with a page’s rank, this is a proprietary Google term and is a measure of howimportant Google considers a page to be. This is one of the factors that influences a page’s rank
keywords – the word or phrase that generally means the search term on Google or the word or phrase that you are targeting on any particular website page. It can be made up of a single word but is more usually made up of several words eg. ‘home insurance’, ‘home insurance quotes’, ‘insurance for your home’ are all different keywords
pay per post – where an advertiser pays you to write a post on your blog about a product etc etc with a link to the product maybe
paid links – where you pay someone to put a link on their site that links to your site, or vice versa. Since Google believes that paid links corrupt its goals it claims to penalise sites that they can identify as doing this. How they can identify that someone has paid for a link is a bit controversial. These are considered black hat SEO practises.
organic link – a link that someone places on their site solely because they believe the resource has some value for the user ie. they didnt place it because they were paid to do so. This is what Google wants everyone to do.The organc link is a white hat SEO practise.
page title – the title of the web page is what appears in the browser bar and is contained within the <title> element. Not to be confused with the large and/or bold text that may usually appears as the title of the content in the page – this is termed the page headline
on-page factors – the entities that influence rank that are based on your page/site itself eg. content, title tags, navigation links etc
off-page factors – entities that influence rank located on other websites – primarily this relates to links that point to your pages/site
